Another Update!
After using this workflow on a larger “test” project, it become obvious that the “Remove Irrelevant Identity Data” Group (shown in post 12 of this thread) was correctly removing the unwanted data BUT was also deleting duplicates of values i did want to keep.
In simple terms…
List A (Full list)
1
1
2
3
1
List B (Items to remove)
2
3
Final List
1
(only 1 “1”, not 3)
In my original test i used 2 drawings and both had different suitability statuses (‘S2’ and ‘S4’) so i didnt run into this problem as it kept them both anyway.
To get around this issue i used the following approach (replacing the SetDifference node);
Just wanted to put this out there for anyone that may use this!
Thanks to @Jeff_Shaver for this idea (Source: List difference with Python)
